FREEZE SC

Use the FREEZE SC command to prohibit all link managers, such as LINKMON

processes and Pathway/iTS TCPs, from sending requests to a server class.

If a server has incomplete requests (requests for which links have not yet been

granted) or outstanding requests (such as an active dialog), the PATHMON process

cannot freeze the server class until after these requests complete. While waiting for the

requests to complete, the server is in the FREEZE-PENDING state, and no new

requests can be initiated.

If no incomplete or outstanding requests exist for any server in the server class, the

PATHMON process immediately freezes the server class.

Continuation

To freeze all server classes, initialize the ZSERVERCLASS field in ZPWY-DDL-SEL-

SC to ZPWY-VAL-ALLSC. Reissue the command continually by using the context

token returned by the PATHMON process until no data is returned in the reply buffer.

When you specify, responses are only returned for server classes in the THAWED

state. For more information, see Specifying Continuation on page 3-17.

Command Syntax

For tokens that may be present in the command and response buffers but are not

listed, see Unlisted Tokens on page 3-29. For descriptions of tokens and fields, see

Section 4, SPI and EMS Standard Definitions through Section 7, ZPWY-MAP-

Definitions.
